My goal is the discovery of key gene networks that affect sperm mobility phenotype. The discovery of sperm mobility and the analysis of this trait resulted in three outcomes that were wholly unexpected in the mid-1990s: (1) a patent followed by technology transfer, (2) a model explaining in vivo...

Dr. Johnson has been a professor in the Department of Rangeland Ecology and Management at Oregon State University since 1982. His research examines the spatial behavior and movement of livestock on landscapes. He also develops models that predict animal distribution and use. Dr. Johnson is...

Beef cattle nutrition and management; low-quality forage utilization.

The underlying theme in most of the research conducted within the last 10 years has been in comparative embryology with an emphasis in the extracellular matrix-degrading proteinases, in particular, the plasmin system, and to a lesser extent, the matrix metalloproteinases. Because of a potential...

Spatial and temporal dynamics of sagebrush and juniper woodlands in the Intermountain Region with an emphasis in fire.

(1) Mechanisms of action of ovarian steroid hormones in regulating uterine gene expression as related to luteal function and embryonic mortality on the cow, ewe, and gilt.
(2) Neuroendocrine basis for sexual behavior in sheep.
